Authorities said three people, including a 3-year-old and the family dog, woke up to smoke and flames coming from the garage of the home on Valleybrook Road Southeast.

The fire spread into the living room after a vapor explosion blew out the wall between the garage and living room, a news release said.

Investigators said the fire consumed the garage and there is smoke damage throughout the home.

According to Assistant Fire Marshal Ron Bailey, the homeowner had worked on his motorcycle in the garage prior to going to sleep and shutting the garage door.

"That most likely created gasoline vapors within the enclosed garage," Bailey said. "It looks like the (lawn sprinkler) water pump, which is also located in the garage, most likely sparked upon starting and ignited the vapor."
